This invention relates to a new and imroved closure for milk bottles and the like. gevices of this character now known to the art are,'in every instance, diliicult to place on the bottle or remove therefrom, and the main object of m invention is to provide a device which can placed on a bottle eas1ly and quickly, and removed therefrom in like manner.

Another object is to rovide a closure which can be used repeatedly. Other ob ects and advantages relate to the details and orm of parts, all as will more fully appear from the following description taken in connection with the accompanying drawing, in which Figure 1 is a top plan view.

Figure 2 is a section on line 2 2, Figure 1.

Figure 3 is a side elevation.

Fi ure 4 is a section similar -to Figure 2 showing a modied method of forming the end of the skirt of the device.

Figures 5 and 6 are views similar to Figure 2 illustrating two different ways of operatlng the device.

My invention consists of the combination of a cap -1- and a sealing disk -2-. The cap -1- is preferably formed of paper stufficiently thin so that it will remain at all tlmes easily pliable, and impregnated with paraffin or the like to make it impervious to li uid. The sealing disk -2 is circular in orm and of a size to fit tightly on the shoulder 3- re ularly found on the insideof the mouth o? a milk bottle 4-, and is preferably made of stiftl cardboard.

The cap -1- is formedinto a cup shape, preferabl by forming folds or plaits -5- in the sidyes causing t e same to conform to the general shape of the top of the bottle -4 and has the end of the skirt -6 return bent on itself to retain the folds -5- in position. This latter operation may be performed by'bending back the skirt -6- on the outside thereof', as shown .at -7- in Figure 2, or, by bending the skirt -6 on the inside thereof, as shown at -8- in Fi ure 4.

e cap -1 is of sufciently great diameter so that when it is in position on a bottle, it is in circumferentially spaced relation to the outside peripher and4 top of the bottle top -4, as can per aps he more easily seen in Figures 2, 4 and 5. The skirt -6- extends downwardly from the top of the bottle a distance approximately equal to the diameter of the bottle neck -9.

In operation my device functions as follows The cap -1- is placed loosely on the bottle top -4-. A disk -2- is then placed on top of cap -1- and pressed down into position on shoulder -3-. The cap lbeing easily pliable, will conform to the shape ofdisk 2- and shoulder 3 and will coact with disk -2- to hold the latter firmly in position. The cap and disk in sealing position are shown in Figures 2 and 4. In this position the bottle is tightly sealed against escape ofliquid, and the pouring lip l0 is protected against any contamination.

When it is desired to remove the cap from the bottle, it being in spaced relation to the to of the bottle 4-, easily adapts itself to a nger-hold, as shown in Figure 5, by means of which it may be lifted off the bottle.`

It is also possible, and perhaps preferable, to grasp the skirt 6 and pull the same downward. This lwill cause the to'p of the cap to rise and lift the disk -2- from its seat on shoulder -3-, after which the cap may be lifted from the bottle. The construction and operation of the device is such that it may lhe used again and again without injury, for it is not necessary to use a knife or other means to break the seal, as is usually the case with devices of this character, nor is there any liability of spilling any of the contents nf the bottle when the cap is being remove Altho I have shown and described a specific V ing skirt extending downwardly along the bottle neck and being freeto move vertically in relation thereto in both directions, and a.

* sealing disk suprposed on said pliable member and coacting therewith to seal the mouth of the bottle.

In Witness whereof I have hereunto Set my hand this 28th day of July, 1927.
